Basic characteristics of each soil type # fig2, fig.height = 3, fig.width = 3, fig.align = “center”
Soil respired CO2-13C ()
Respiration Rate Over Time
Mineralization and Mineralization Rate Over Time
Cumulative Soil Derived CO2-C over time (Control v Glutamic Acid)
Respired C Source over time “Base” Respiration is the control (+H2O) respiration. Base + primed = total soil derived CO2 Base + primed + amendment = total CO2 respired
Bar plots cumulative to 168 hrs
DOC relationship with respired C Strong relationship between DOC and control respiration (except for LATR eCO2) Weaker relationship between DOC and glutatmic acid soil resp or primed C
